In this paper, we proposed a novel marker-based tangible interface for various users to manipulate the object with intuitive and simple approaches during an authoring application of augmented reality. The proposed method makes use of marker as intuitive interface to obtain 3D geometric information of 3D reconstruction. 3D geometric information of an object surface is acquired by touching the object directly with the proposed tangible interfaces. The tangible interfaces not only support 3D reconstruction for graphical modeling but also offer features information which is used for augmented reality. Finally, we verify efficiency of the proposed method with demonstration of an augmented reality application using the proposed method.

In transforming the original image frames into two-bit representations, the typical two-bit transform (2BT) needs to calculate the variances of the local blocks. This calculation of variances inevitably involves multiplication operations and renders the computational complexity of typical 2BT somewhat high. In this paper, we propose a constrained two-bit transform (C2BT) for low complexity motion estimation (ME). By exploiting the advantages of the typical constrained one-bit transform (C1BT) and the typical 2BT, the proposed algorithm significantly reduces the computational complexity of transformation of image frames into two-bit representations. Experimental results show that the proposed algorithm enhances the ME accuracy by 0.35dB and 0.28dB compared with the 2BT-based ME and the C1BT-based ME, respectively.

A 60GHz communication can be a best solution for high capacity wireless data communications such as uncompressed HD video streaming. However, due to highly directional characteristics of 60GHz frequency band, the line-of-sight (LOS) path blockage should be avoided to maintain the peer-to-peer connectivity. In this paper, we propose a novel 60GHz relay system for blocking avoidance, and show the experimental results of the prototype system employing proposed relay scheme which outperforms the conventional LOS communication system, and also present that video streaming is seamless when LOS is blocked with a prototype system.

This paper proposes a new noise suppression method to reduce zoom noise generated when audio signals are recorded with a digital camera. The proposed method is based on multiband spectral subtraction that can suppress spectral components of noise related to reference zoom-noise in the modified discrete cosine transform domain. In particular, in the proposed method, each frame is classified as either a noise frame or a non-noise frame, and depending on this classification, the reference zoom-noise is updated and the degree of suppression is controlled. It is shown from performance evaluation that noise due to a zooming operation of digital cameras is successfully suppressed while maintaining audio quality.

Internet increasingly suffers congestion on the server side, particularly due to ever-increasing demand for high-quality audio/video streaming. CCN is considered as an important networking paradigm which can efficiently address such traffic explosion issue. Although early implementation of CCN protocol is available through CCNx open source project, current version lacks efficient support for real-time streaming applications. In this paper, we propose an enhanced mechanism for the support of real-time content streaming service in CCN, and present experimental results demonstrating its effectiveness.

As a cornerstone of VANET (Vehicular Ad Hoc Networks) system, vehicles need to have awareness information about other vehicles in the vicinity for safe driving. In this paper, we propose a lightweight geocast-based piggybacking mechanism for cooperative awareness applications in VANET. We leverage only one-hop beacons to construct both local and extended traffic views for drivers. Since multi-hop communication does not scale well, consequently our proposed scheme only exploits single-hop beacons to provide the same comparable functionality as multi-hop communication would do. The goal is achieved at the expense of a small piece of additional information (traffic classes) in the scheduled beacons. Geocast-based piggybacking has a twofold advantage over traditional flooding-based approaches; it serves as virtual multi-hop communication paradigm and it avoids broadcast storm problem.

In this paper, an automatic method for extracting visual saliency based on selective integration of feature maps in frequency domain is proposed. Feature maps are calculated by measuring the Bayes spectral entropy. In order to extract visual saliency effectively, feature maps are first generated from three images separated into Y, Cb, Cr channels, respectively. Then, by selectively integrating feature maps, visual saliency is finally extracted. Experimental results have shown that the proposed method obtains good performance of visual saliency under various environments containing multiple objects and cluttered backgrounds in natural images.
